Cross-cabinet server memory pooling method, apparatus and device, server, and medium

A cross-cabinet server memory pooling device, comprising:

• a memory, configured to store a computer program;
• a processor, configured to implement steps of a cross-cabinet server memory pooling method when executing the computer program, wherein the cross-cabinet server memory pooling method comprises:
• determining that a memory allocation request for a first target device sent by a target cabinet outside a cabinet where a server is located, is received, then transferring a control authority of the cabinet where the server is located on the first target device to the target cabinet, so that the target cabinet is capable to use a memory of the first target device;
• determining that a memory reading request sent by the target cabinet through a communication device for data to be read in a memory of the first target device, is received, then sending the data to be read in the memory of the first target device to the target cabinet through the communication device;
• and
• determining that a memory writing request sent by the target cabinet through the communication device for the memory of the first target device, is received, then writing data to be written sent by the target cabinet through the communication device into the memory of the first target device;
• wherein the cross-cabinet server memory pooling method further comprises:
• determining that a memory space of the server is insufficient, then determining whether there are remaining memory resources in other servers in the cabinet where the server is located;
• determining that there are no remaining memory resources in other servers in the cabinet where the server is located, then sending a memory allocation request for a fourth target device to the target cabinet outside the cabinet where the server is located;
• determining whether a successful allocation signal fed back by the target cabinet is received;
• and
• determining that the successful allocation signal fed back by the target cabinet is received, then sending a memory usage request to the fourth target device applied in the target cabinet.

A server, comprising a server body and a cross-cabinet server memory pooling device, which is connected with the server body, wherein the cross-cabinet server memory pooling device is configured to:

• determine that a memory allocation request for a first target device sent by a target cabinet outside a cabinet where a server is located, is received, then transfer a control authority of the cabinet where the server is located on the first target device to the target cabinet, so that the target cabinet is capable to use a memory of the first target device;
• determine that a memory read request sent by the target cabinet through a communication device for data to be read in a memory of the first target device, is received, then send the data to be read in the memory of the first target device to the target cabinet through the communication device;
• and
• determine that a memory write request sent by the target cabinet through the communication device for the memory of the first target device, is received, then write data to be written sent by the target cabinet through the communication device into the memory of the first target device;
• wherein the cross-cabinet server memory pooling device is further configured to:
• determine that a memory space of the server is insufficient, then determine whether there are remaining memory resources in other servers in the cabinet where the server is located;
• determine that there are no remaining memory resources in other servers in the cabinet where the server is located, then send a memory allocation request for a fourth target device to the target cabinet outside the cabinet where the server is located;
• determine whether a successful allocation signal fed back by the target cabinet is received;
• and
• determine that the successful allocation signal fed back by the target cabinet is received, then send a memory usage request to the fourth target device applied in the target cabinet.
